I feel used and ripped off

Good day

I had a problem with my Renault Kwid of which the tow guy advised me to take my car to the AAA Recovery Auto Repairs & Services as that guy was very good with Renaults since the Renault dealership failed me straight. the car was collected on the 3rd of May from my home and towed to Duncanville. Marius did alert me when he did receive the car, told me had diagnosed it and that the clutch was worn out and was a leaking pipe and that he also do a full service on the car once. I agreed. On the 13th June he called to say the car is ready for collection and I arranged with him if I can come and collect it on the 16th June, he agreed. the first thing that got caught my ear was the sound, it sounded like a motor bike, but I decided to keep quiet. I asked for the tax invoice so I can make payment, he answered by saying that lady in not in cos it's a public holiday but I must please make an immediate payment otherwise he will be in trouble releasing the car without any money and yet I paid without the actually tax invoice, After I left the place I still had to fix the exhaust that was leaking and pay more. I have begged and pleaded for my tax invoice to be sent throuh Till today I still await the tax invoice which includes all the things he claimed to have fixed
